To all whom itnuty concern Be itknowu that I, WILLIAM Ducnnmraof Boston,in the county of Suffolk and Commonwealth of Massachusetts, haveinvented a new and. useful Iraprovement in the Manufacture of Boots andShoes,

namely, a Machine for Molding, Rounding, and Ghanneling tbeSolesthereof, previous to their being applied to the uppers; and 1- do herebydeclare. that the following is a full, clear,' and' vexact descriptionof the same, due reference being had to the drawing accomvpanyingandforming part of this specification.

Figure 1 is a front elevation. Figure 2fis a side elevation.

Figure 3 is a plan'of thebed-plate or table of the machine.

Figure 4 is a vertical central. longitudinal section of the same. Y Y.

Figure 5 isaI perspectiv view ofthe segmental rotating block andleverar1,'with the cutting head-v block and carriage attached thereto.'

Figures o, 7, s, aan@ 1o winte referred wenn explained as thedescription of the invention may require.

. Figure 11 is atrausrerse sectioirof the formingiast.

Figure 12 is a; longitudinal section of' self-adjusting joint.

The object of my -invention is to perform with ouemachine, and at thesame time, worl'r, which, by the present mode, requires three, andsometimes four,

machines, namely, molding, rounding, andv channeling,

technically sorcalled, the soles of boots and 'shoes previous to theirbeing secured to the uppers.

The first operation 'consists irl-molding thesoles in such Yn. mannerthat the uudersurtaee will conform vto the shape ofthe b'ottomof thelastused; the second inouttiug round the edge ofthe sole to the requiredlshape; `the third in cutting a gioov'c or channel to receive thestitches, it' 'sewed; if pegged lor nailed, the channel' can be alteredto suit.the work.

The frame of the machine'is made in four' parts; as shown in dig. 2, onefront, one hack,4 and two side pieces, marked an, a, securcd'together inthe u sual manner. l c

-On each side of the framo'is a pulley, aorer which passes a chan,having one end fastened to the lower cross-bar of the mulder-frame b 1:,and the other tothe weight or counterpoise b. This couuterpoise is madeof suicient weight to drawup and keep thc frame b b in the positionshown in tig. 1.

, At the back or inner end of theit'op side the curved bar or goose-neckissccurcd, marked @having on its outer end-the'box-bearing a?, throughwhich-the upright or moitier-shaft b passes.

On the top ofthe Aframe n, a` res-ts -the bed=platexorA table ddfhavin'g a centml-longtudnal recess in its upper surface forthe.reception ofthe slidingbar or carriage (11,.towhlch is attached theforming-last or,

and p1, (see 'iig. 4,) extending upward until they pass the center oi'the screw d, there being a 4circular cavity in. the upper end of cach topreventv the screw from coming in contact therewith.

To iind nthe position anddimeusions of the slot in the inner end ofthecarriage, it will be necessary to ilnd the cxtreme difference in thelength of the work i that is to say, if the shortest forming-'laster bedbe -six inches long'and the longest,be ten, the slot will haveto be fourinches long, to which must he added the space taken up by thetraversing-nut if. If-the nut .betwo inches wide, theV slot must be-sixinches long, and its inner end be-iive inches from the center ofthehollow screw in' the outer end of the carriage d. To nd the positionsof the tripper-blocks p and p* s on the shippingbard, (sec iig. 4,)place the outer end of thecariiage din line with the front of thehedplate d d, and place the'pulleys d ont of gear; then`thetripper-block p must 4he so placed that its outer face will touch theiunerfacc of the'clntch p, and the i distance between the inner face ofthe tripper pl andthe outer face of the traversing-nut d* will be thesame as the distance between the centers of the fast'- ening-bolts inthe forming-last b3,

These springs graduate the pressure, giving heavy or light, as they arecompressed by nuts placed beneath thern for that purpose.

Below theworking joint` is an,- other projectingstud, '11?, haring a ,slotinthcend to receive the shatt of the shipper-N. This stud, while it allowsthc shipper to m'ov'c back and forth freely,

acts as a bra -e against any side motion or strainin shipping orotherwise.- Projecting out from theleft hand bearing n* is a har,`u,bent in such a formv that its outer end runs parallel with itsfiwe;'this braces the shipper. while performing its work.' On the lowerend of the shipper b is a widey plate, on thc'inncr face These camsarose `fitted onY of 'whiohis an inclined plane,`mad in su'ch propor`tion that it will act in unison with tl1e`inclined plane n4 on theontcrface of the canili. .The crooked bar At the end of the scroll on theface'of the cam l is achip, n", its frontendbeing wpdge-shaped, shown atl, iig. 10. This chipor block, actingagainst the projecting lip n onthe. end ofthe bar 17, throws the cam L5 out of gearand the cam 1 ingear, thus relieving the pressure, when, by the action of thecounterpoise bl, the'molderg'arne is drawnup 'andassunres the pcf sitionshown'in iig." 1.- f i f?, iig. 5, is a perspectivevicw of thecutting-head carriage. -adixed in working order to the arm Y f, asheretofore described.

To theinner end ot' .this carriageattached by a pivoijont' which allows it-torotate freely to rightad lett, isfthe carrier 'f, in'which thecutting-head f5, governerhlpy the spiral springs yly, moveshack andforth. 0n the inner end of the carrier, raiscda trifle above the sure;

This is done to easethe knife when turning' round thetoe end of the sole, the angle ofwhichis sometimes veryncute. Y c

The follower 'm5 is the width of the ronnding-knife narrower than theleading ingerm.' This is done toallow the knife to be drawn bacloandthnsgivc the molder'roorn Jto perforrn its work.

On this outer endV isaiiixcd the'carrier g", in which 4thechannel-cutter gis placed, there being for this purpose a dovetailedgroove let into the carrier, in' which the channel-cutter is fitted insnch a mannertha't it will traverse freely.

At the upper'end, on the face, andhaving its ful-y crum on the outerside of the carrier g', is the arm or 4 leverl g-, to' wl1ich, bymenns'of a connecting-link, is -ttached the,channel-cntter.
